We describe the category of regular holonomic modules over the ring D[[ℏ]] of linear differential operators with a formal parameter ℏ. In particular, we establish the Riemann-Hilbert correspondence and discuss the additional t-structure related to ℏ-torsion.

We describe the category of regular holonomic modules over the ring D[[ℏ]] of linear differential operators with a formal parameter ℏ. In particular, we establish the Riemann-Hilbert correspondence and discuss the additional t-structure related to ℏ-torsion.
